[aprssig] parked cars

Correct. In fact, I went a little further.. I placed a reed relay 
connected to the accessory circuit. The GPS, a modified TripMate, is on 
24/7 while vacationing.. When I shut the car down, the reed relay 
interrupts the data flow from the GPS and the CLEAR action is after the 
first BLTs, and the last one will continually send the last position 
once every 30 minutes..
